Monitor Core Tension for Better Delivery Position

This drill teaches you to monitor core tension in the delivery position so your body can drive the release instead of your hands and arms taking over. Many golfers can place the club and arms in a decent-looking delivery position on camera, but the motion still fails because the torso is not loaded. If your chest and hips are moving together with no stretch or resistance through your midsection, you have very little stored energy to unwind through impact. That usually leads to an arm-dominated hit, early throwing of the club, or a transition that looks good in pieces but does not transfer into a powerful strike.

How the Drill Works

The goal is not just to arrive at a certain checkpoint with the club. You want to arrive there with tension across the core so your body has something to release. In a good delivery position, your lower body and upper body are not simply stacked and turning as one unit. There is a subtle but important separation that creates a loaded feeling through your trunk.

When you rehearse this correctly, you should feel:

A slight crunch or contraction on one side of your abdominal wall
A stretch through the opposite side, often into the side of the torso and back
Your legs, torso, and arms connected rather than your arms moving independently

One helpful way to create this is to move into delivery, then add a small amount of side bend and torso orientation so the upper body feels a bit more “back” relative to the lower body. Tyler often refers to this as a bit of a turtle shell feel. You are not trying to make a huge move. You are simply trying to organize your body so the core is loaded and ready to unwind.

This concept is especially useful in pump-style transition drills. As you rehearse the club dropping into delivery, the pump should not be a pure arm pull-down. It should be a motion where the core tension builds while the arms are being delivered. Once that tension is there, you can let the release happen naturally with the body instead of forcing the strike with your hands.

Step-by-Step

Start in a normal setup. You can do this without a ball at first. Make a slow backswing to the top or simply place yourself near the top of the swing.
Move into your delivery position. Bring the club and arms down to where you would normally rehearse the shaft approaching impact. Do not worry only about where the club is. Pay attention to what your torso is doing.
Check that your chest and hips are not matching too closely. If they are pointing in the same direction with no resistance in your trunk, you are likely too “flat” through the core and not storing anything useful.
Add the core load. From delivery, feel a small amount of side bend and upper-body organization so your torso feels slightly more wound against the lower body. This is where the crunch on one side and stretch on the other should begin to appear.
Pause and identify the sensations. Feel your abs working. Feel the stretch through the opposite side of your torso and back. Notice whether your legs feel connected to your arms through your trunk.
Release from that tension. Once you have the loaded feeling, turn through and let the body unwind. The release should feel like it comes out of the torso, not from a last-second hand throw.
Repeat with a delivery pump. Make a backswing, then pump down into delivery two or three times. With each pump, feel that the core tension builds as the arms fall into place.
On the final pump, swing through. Do not force the club with your arms. Let the stored tension unwind and carry the strike.

What You Should Feel

This drill is all about replacing a “position-only” mindset with a loaded-position mindset. A few key sensations can help you know you are doing it correctly.

Core engagement, not just arm placement

If your arms look good but feel disconnected from your body, you are missing the point. In a strong delivery position, your arms should feel supported by the movement of your torso, not manually dragged into place.

A crunch on one side and stretch on the other

You should feel one side of your midsection shortening while the opposite side lengthens. That asymmetry is a sign that your body is organizing itself to release powerfully instead of spinning level or sliding aimlessly.

Connection from the ground up

Your legs should feel tied into the motion. When the drill is correct, your lower body, core, and arms work together. When it is wrong, the arms feel like they are doing all the work while the body follows late.

A release that happens instead of one you force

The best checkpoint is what happens after delivery. If you have loaded the core properly, you should feel like you can simply unwind. If you feel the need to “hit” from the top or throw the clubhead, you probably did not create enough tension.

Common Mistakes to Avoid

Matching chest and hips too early so there is no separation or stored tension in the trunk
Pulling the arms down actively to manufacture delivery instead of letting the body organize the motion
Focusing only on what it looks like face-on without checking whether the torso is actually loaded
Overdoing the motion with excessive tilt or twist instead of a compact, athletic load
Trying to hit from the top because there is no tension to unwind through impact
Making the pump drill an arm drill rather than using it to build core tension during transition

How This Fits Your Swing

This concept matters because the delivery position is not just a shape. It is a moment where your body should be prepared to release the club efficiently. If you can get the shaft and hands into a solid-looking spot but your core is passive, the downswing often becomes an arm pull-down followed by a handsy hit. That pattern may occasionally find the ball, but it usually struggles under speed.

When you learn to monitor core tension, your transition improves in a deeper way. Your arms stop racing independently. Your body begins to swing the arms instead of the other way around. The release becomes more rotational and less manipulative. That gives you a better chance to shallow the club, sequence the downswing properly, and deliver the club with more consistency.

This is why the concept blends so well with transition drills like the delivery pump. The pump is not just there to place the club in space. It trains you to feel how the body loads delivery and then releases from it. If your transition tends to get steep, rushed, or overly handsy, monitoring this core tension can be the missing link.

As you practice, keep asking yourself one simple question: Do I have something stored in my core that I can release? If the answer is yes, your delivery position is likely becoming functional rather than cosmetic.
